PlayerPrefs

Stores and accesses player preferences between game sessions.

On Mac OS X PlayerPrefs are stored in ~/Library/Preferences folder, in a file named unity.[company name].[product name].plist, where company and product names are the names set up in Project Settings. The same .plist file is used for both Projects run in the Editor and standalone players.

On Windows standalone players, PlayerPrefs are stored in the registry under HKCU\Software\[company name]\[product name] key, where company and product names are the names set up in Project Settings.

On Web players, PlayerPrefs are stored in binary files under ~/Library/Preferences/Unity/WebPlayerPrefs on Mac OS X and %APPDATA%\Unity\WebPlayerPrefs on Windows. There is one preference file per Web player URL and the file size is limited to 1 megabyte. If this limit would be exceeded, SetInt, SetFloat and SetString will not store the value and throw a PlayerPrefsException.
